Inductive Kick-Back Protection
Diode D1 and capacitor C1 serve as inductive kick-back pro-
tection to limit negative transient voltage spikes generated on
the input when the input supply voltage is abruptly taken to
zero volts.
Diode D2 and capacitor C2 serve as inductive kick-back pro-
tection to limit positive transient voltage spikes generated on
the output when the input supply voltage is abruptly taken to
zero volts.
Off Test Point
The Off test point provided on the LM5050-1 evaluation board
is used to control the LM5050-1 operation. The Off test point
is connected directly to the LM5050-1 OFF pin. See the
LM5050-1 datasheet for more details.
To enable the LM5050-1 apply a voltage less than 0.8V to the
30133416
Off test point, connect the Off test point to GND, or leave the
Off test point open (default). If the Off test point is left open,
FIGURE 3. OFF pin vs GATE
the LM5050-1 OFF pin internal pull-down will ensure that the
LM5050-1 becomes operational.
To disable the LM5050-1 apply a voltage greater than 2.0V to
the Off test point.
